在给定服务器的IP地址的情况下,如何使用C#测试与服务器的连接？

using System;
using System.Net.Sockets;

class Program
{
    static void Main(string[] args)
    {
        string ipAddress = "192.168.1.1"; // 替换为实际的 IP 地址
        int port = 80; // 替换为实际的端口号

        try
        {
            TcpClient tcpClient = new TcpClient(ipAddress, port);
            Console.WriteLine("已成功连接到服务器");
            tcpClient.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine($"无法连接到服务器: {ex.Message}");
        }
    }
}

using System;
using System.Net;
using System.Net.Sockets;

class Program
{
    static void Main(string[] args)
    {
        string ipAddress = "192.168.1.1"; // 替换为实际的 IP 地址
        int port = 80; // 替换为实际的端口号

        try
        {
            Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            socket.Connect(IPAddress.Parse(ipAddress), port);
            Console.WriteLine("已成功连接到服务器");
            socket.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine($"无法连接到服务器: {ex.Message}");
        }
    }
}
